Can you look at the source code in the repos and make any sense of it?
Are there open issues connected to the repo, that you think you could make some headway with?
If you have 0 experience writing code, I think contributing to an existing project isn’t a good way to start. Better to text a textbook and work through some exercises, and do a few small projects of your own, before trying to join an existing team where as a total newbie, you’ll be a burden. Note that “small project of your own” can involve forking something that exists and making your own changes or additions. That doesn’t require much attention from other people.
Then, contribute once you feel you are ready to contribute.
